The Dreamcast is still our favorite. Sega Dreamcast came with VMU memory cards. These were more than just a memory card. This was a "Visual Memory Unit", which is an official Sega memory cards but also features a screen that allows you to play additional games, unlock special features and use special characters. Finally, you can now save games on your Dreamcast! *Authentic Sega Brand VMUs were tested. VMUs can show cosmetic age, be Japanese-made and will work with all Dreamcast controllers and consoles.
